7 * 4 = 28
28 + 5 = 33
33 / 3 = 11
11 - 7 = 4
The number she thought of is 4

In ratios, 'things go with the same things', so recliners have to be both in the numerator or denominator. The 8 is misleading. That's the total, and the problem is all about recliners and couches only
Answer:
The answer is 1/216
Step-by-step explanation:
The probability of getting a 2 on a six-sided number cube is 1/6 because the number "2" appears on just one out of the six faces.
Since, the probability of getting a 2 in the first throw is independent of the probability of getting a 2 in the subsequent throws, we multiply these probabilities:
P (2, 2, 2) = 1/6 x 1/6 x 1/6
P = 1/216
= 3 - 3cos x - 2(1- cos^2 x)
= 2cos^2 x - 3cos x + 1
=(cos x -1)(cosx - 1/2)
now cos x = 1 or cos x= 1/2
draw a graph we get = + ve values
hence .. 0 ,180,360 and 60,240, degrees in range x<2pi
